Question

How many copies of DNA are produced after DNA replication in a cell is completed?

billions of copies or one copy?

Answer 1

After DNA replication, two copies of DNA are produced to ensure each new cell has a complete set of DNA.

Step-by-step explanation:

After DNA replication in a cell is completed, there are two copies of DNA. Each cell contains a set of chromosomes, and when cells replicate, all the chromosomes are copied once to ensure that each of the two new daughter cells has an identical set of DNA as the parent cell. For instance, during the synthesis phase (S phase) of the cell cycle in humans, the amount of DNA within the cell precisely doubles, creating two sister chromatids for each chromosome.

Answer 2

One Copy

Step-by-step explanation:

Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules.

Polymerase-Chain-Reaction: each of these strands can be used to create two new copies, and so on, and so on. The cycle of denaturing and synthesizing new DNA is repeated as many as 30 or 40 times, leading to more than one billion exact copies of the original DNA segment.
